Answer
Based on the observations:
Metal P produced bubbles very slowly and some metal remained, indicating low reactivity.
Metal R produced bubbles slowly with no metal remaining, indicating medium reactivity.
Metal Q produced bubbles quickly with no metal remaining, indicating high reactivity.
Metal S produced bubbles very quickly with no metal remaining, indicating the highest reactivity.
Therefore, the order from least reactive to most reactive is: P, R, Q, S.
